[0013] Figure 1 A flowchart of a method for dynamically activating a dedicated lane provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] An embodiment of the present invention provides a method for dynamically enabling a dedicated lane, the method comprising the following steps:

[0016] S100, based on the first target location and the second target location, obtain several key paths from the first target location to the second target location, wherein the first target location is a preset starting point and the second target location is a preset end point; it can be understood that: when holding a sports event or a large-scale conference, the preset starting point refers to the residence of the participants of the event or conference, and the preset end point is the competition venue or conference venue; for example, when holding the Asian Games, the residence of the participants is the Asian Games Village.

[0017] Specifically, several key paths from the first target location to the second target location are obtained through the road network matching model and the A-star algorithm, and the key paths refer to several paths that can be used for travel from the first target location to the second target location; those skilled in the art are aware of the specific implementation methods of the road network matching model and the A-star algorithm, which will not be repeated here.

[0018] As described above, by determining the first target location and the second target location, path acquisition and path planning can be performed, and several shorter key paths can be obtained through the A-star algorithm to obtain the traffic flow of each section in several key paths, and then the lanes can be reasonably planned to ensure the safe and on-time arrival of the target vehicle.

[0019] S200, according to the several road sections corresponding to each key path, the road section screening is performed to obtain a key road section list A = {A1, A2, ..., A i , ..., A m}, where A i is the i-th key section, i=1, 2, ..., m, m is the number of key sections, and the key section is any section in several key paths whose historical traffic flow meets the preset conditions; it can be understood that: the section in several key paths whose historical traffic flow meets the preset traffic flow threshold is the key section.

[0020] In a specific embodiment, in S200, A is determined by the following specific steps: i :

[0021] S201, obtaining a first section list set C corresponding to a plurality of key paths = {C1, C2, ..., C j , ..., C n}, C j ={C j1 , C j2 , ..., C jp , ..., C jq(j)}, where C jp is the pth first section corresponding to the jth critical path, j=1, 2, ..., n, n is the number of critical paths, p=1, 2, ..., q(j), q(j) is the number of first sections corresponding to the jth critical path.

[0022] Specifically, the first road section is any road section in any key path; wherein a road section can be understood as: a road section is between an intersection and the nearest intersection.

[0023] S202, according to C and C j , perform deduplication processing on all first road sections, and obtain the second road section list D = {D1, D2, ..., D e , ..., D f}, where D e is the e-th second section, e=1, 2, ..., f; f is the number of second sections.

[0024] Specifically, the second road section refers to any remaining first road section obtained after deduplication processing is performed on all first road sections; for example: there are two key paths in total, the first key path consists of section one, section two and section five, and the second key path consists of section three, section four and section five. When deduplication processing is performed, one of the sections five is deleted, and the second road section list obtained consists of section one, section two, section three, section four and section five.

[0025] S203, obtain D e The corresponding traffic flow R in the preset historical time period e ; For example: the preset historical time period can be the past seven days before the event starts.

[0026] S204, when R e ≥R0, R e Confirmed as A i , where R0 is a preset traffic flow threshold; for example, the preset traffic flow threshold may be set based on statistical historical traffic flow data.

[0027] As mentioned above, by performing road section screening, a list of all non-repetitive key road sections containing several paths can be obtained, so as to count the historical traffic flow of each key road section, making the traffic flow statistics of each key road section more accurate, so as to screen out the road sections with a traffic flow not less than a preset traffic flow threshold, and provide a basis for the installation position of the lane indicator screen.

[0028] S300, according to A, obtain the lane indication screen list B corresponding to A = {B1, B2, ..., B i , ..., B m}, where B i A i The corresponding lane indicator screen refers to an LED electronic indicator screen pre-set for each key section; for example: based on the direction from the first target location to the second target location, a corresponding lane indicator screen is set at the starting point of each key section, and can also be set on a traffic light frame, and multiple lane indicator screens can also be set on one side of each key section.

[0029] Specifically, the LED electronic indicator screen refers to an indicator screen used to display several lanes of the corresponding key section, and to indicate whether vehicles and personnel can pass through the preset special lanes in the key section; for example: the LED electronic indicator screen displays "Specially for target vehicles in this period" or "Social vehicles are allowed to be borrowed in this period" at the corresponding preset special lane, and switches between the two modes according to the conditions, wherein the target vehicle refers to the vehicle used by the personnel participating in this meeting or this event when going to the second target location.

[0030] Specifically, the preset dedicated lane refers to a lane that is pre-set according to the instructions of the lane indicator screen and is only used for the target vehicle to travel when enabled.

[0031] As mentioned above, through the pre-set lane indicator screen, the traffic situation can be displayed in the corresponding lane indicator screen in time when the road condition changes, so that the personnel of the target vehicle and social vehicles can promptly identify the traffic conditions of several lanes corresponding to each lane indicator screen, to indicate whether the personnel of social vehicles can pass through the preset special lanes, and to ensure that the target vehicle has priority passage and arrives safely and on time.

[0032] S400, when A i The corresponding real-time vehicle average speed is lower than A i The corresponding preset critical average speed and the target vehicle is in A within the preset time i When passing through A i The preset lane is activated and the activated preset lane is displayed on B i It can be understood as: if the preset dedicated lane is already in use at this time, the preset dedicated lane will remain in the enabled state.

[0033] Specifically, A i The corresponding preset key average speed is based on A i The corresponding historical average vehicle speed or A i The corresponding road types are pre-set; for example, the main roads in the urban area are divided into low-grade sections, and the elevated expressways are divided into high-grade sections.

[0034] Specifically, A i The corresponding preset key average speed meets the following conditions:

[0035] V i =V 0 i ×θ i , where V i A i The corresponding preset critical average speed, V 0 i A i The corresponding historical average vehicle speed, θ i The default A i The corresponding proportionality factor.

[0036] Furthermore, when A i According to A i When the corresponding road grade is pre-divided into low-grade sections, θ i The value range of is 0.75-0.85; by setting the proportional coefficient within this range, the preset critical average speed is less than A i The corresponding historical average vehicle speed is at a reasonable value, that is, when the real-time average vehicle speed drops to a certain threshold, the road section is considered to be blocked, in order to cope with the situation where the real-time average vehicle speed changes slightly due to uneven vehicle speeds, and to improve the rationality of road condition judgment.

[0037] Furthermore, when A i According to A i When the corresponding road grade is pre-divided into high-grade sections, θ i The value range is 0.8-0.9; by fine-tuning the value range upward, it can cope with the situation where the expressway sections are generally long and there are more vehicles, which will cause the real-time average vehicle speed to decrease more slowly, thereby improving the rationality of road condition judgment.

[0038] As described above, different dedicated lane activation rules are implemented according to different road section types of key sections. For low-level sections and high-level sections, the corresponding preset key vehicle speeds are compared with the real-time vehicle average speeds to improve the rationality of dedicated lane activation. When the target vehicle passes within the preset time, the preset dedicated lanes are dynamically activated, thereby improving the utilization rate of road resources.

[0039] The following examples are used as illustration:

[0040] A i After cleaning, screening and analyzing the historical vehicle speeds in the city (for example, Hangzhou), the historical average speed on the main roads is 31.16km / h, and the historical average speed on the elevated expressways is 57.17km / h.

[0041] If A i For ground roads, when A i When the corresponding real-time average vehicle speed is less than 25km / h and there will be a race vehicle passing on the road within 10 minutes, A is activated. i The corresponding dedicated lane; when the average speed is not less than 25km / h, and there are more than 15 race vehicles passing through the road within 10 minutes, A lane is activated. i The corresponding dedicated lane.

[0042] If A i For elevated expressway, when A i When the corresponding real-time average vehicle speed is less than 50km / h and there will be a race vehicle passing on the road within 10 minutes, A is activated. i The corresponding dedicated lane; when the average speed is not less than 50km / h, and there are more than 15 race vehicles passing through the road within 10 minutes, A lane is activated. i The corresponding dedicated lane.

[0043] In addition, when a racing vehicle encounters an emergency, several dedicated lanes that the racing vehicle is to pass through are opened in real time according to the request for opening dedicated lanes sent by the racing vehicle.

[0044] In a specific embodiment, the method further comprises the following steps:

[0045] In a specific embodiment, in S400, the following steps are performed to determine whether there is a target vehicle in A within a preset time period: i Onward access:

[0046] S401, according to the pre-collected target vehicle identification corresponding to each target vehicle and the pre-travel path corresponding to each target vehicle identification, a plurality of first vehicle identifications are obtained; the first vehicle identification refers to the vehicle identification included in the pre-travel path. i The target vehicle identifier corresponding to the target vehicle.

[0047] Specifically, the target vehicle identifier is a unique identifier corresponding to the target vehicle: for example, a license plate number.

[0051] S404, according to K g The corresponding position information of the second vehicle and the data information of the map server are obtained to obtain K g The corresponding second vehicle arrives at A i The target duration T of the starting point gi ; It can be understood as: K is predicted by the map server g The corresponding second vehicle arrives at A i The target duration of the starting point, where A i The starting point is when traveling from the first target location to the second target location at A i The starting point of the travel; those skilled in the art know the specific method of predicting the time it takes for a vehicle to reach a certain location based on the vehicle's location information and the map server, which will not be repeated here.

[0052] S405, when there is at least one T gi ≤T0, it is determined that there is a target vehicle in A within the preset time. i Where T0 is the preset duration, for example, ten minutes.

[0053] As mentioned above, by obtaining the second vehicle that has not yet reached a certain key section and the position information of the second vehicle, the driving distance of the second vehicle to the key section can be calculated, and the time to reach the key section can be predicted, so as to predict whether there is a target vehicle traveling on the key section within a preset time period, and dynamically adjust the state of the preset dedicated lane according to the prediction result, so as to reasonably plan the travel of the second vehicle and social vehicles.

[0054] In another specific embodiment, the method further comprises the following steps:

[0058] Specifically, the target fleet refers to a fleet that is collected in advance and includes one target vehicle or multiple target vehicles; for example, when holding an Asian Games event, if there are many people participating in the same competition event, multiple target vehicles will be used as a fleet to drive to the competition venue together.

[0059] S3, when W is an empty set, in A i Close the first dedicated lane and display the status of the first dedicated lane at B i It can be understood as: if no target vehicle is in A within the preset time, i The first dedicated lane is closed when the vehicle passes through the lane, and the first dedicated lane is closed. If the first dedicated lane is already closed at this time, the first dedicated lane will remain closed; the first dedicated lane being closed means that the lane indicator screen corresponding to the first dedicated lane displays "Public vehicles are allowed to borrow during this period".

[0060] S4, when W is not an empty set, obtain the time information list W corresponding to W 0 = {W 0 1.W 0 2, ..., W 0 u , ..., W 0 s},W 0 u = {W 0 u1 , W 0 u2},W 0u1 To obtain W u The first vehicle in the i The starting time, W 0 u2 To obtain W u The last vehicle in A leaves i The starting time of the 0 u1 and W 0 u2 For the predicted time, those skilled in the art are aware of the method of obtaining the preset time based on the vehicle's location information and the map server, which will not be described in detail here.

[0066] As described above, by obtaining the target convoys that will pass through a certain key road section within a preset time period every preset period, the total overlapping time of several target convoys is determined to predict the degree of congestion that will occur on the key road section. When the total overlapping time is relatively long, the second dedicated lane is opened on the basis of opening the first dedicated lane to alleviate the congestion of the target vehicles and ensure that the target vehicles can arrive at the corresponding locations safely and on time.
